3. (20 points) 2. (20 points) An angle bracket having thickness -19 mm is attached to the flange of a column by two 16 mm diameter bolts (see figure). A uniformly distributed load from a floor joist acts on the top face of the bracket with a pressure p-1.9 MPa. The top face of the bracket has length L-200 mm and width b=75 mm. (Disregard friction between the bracket and the column.) (1) Determine the average bearing pressure σ between the angle bracket and the bolts. (10 points) (2) Determine the average shear stress Taver in the bolts. (10 points) Angle bracket
